Abstract
A theory is developed to study shot noise in superconducting (SAS) and hybr id (SAN) junctions with singly occupied Anderson impurity (A) as a weak lin k. The zero-frequency dc component of the shot noise spectral density is ca lculated at zero temperature as a unction of the bias at different Coulomb repulsion strengths (U), and shows a remarkable structure resulting from co mbination of electron-electron interaction and Andreev reflections.
